Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a buffer structure for a CNC bending machine. Background Technology

[0002] CNC bending machines use equipped molds (general or special molds) to bend cold metal sheets into workpieces of various geometric cross-sectional shapes. They are sheet metal forming machines designed for cold-rolled sheet metal processing and are widely used in sheet metal bending processes in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles.

[0003] The existing Chinese patent publication number CN220346929U describes a bending machine feed toughness buffer structure. According to its description, the buffer spring located below the concave buffer plate is fixed during use. In subsequent use, when the thickness of the metal plate to be bent is different, the required buffering force is also different. The fixed buffer spring cannot be flexibly replaced according to the thickness of the metal plate, which will affect the buffering effect of the device when bending different metal plates in the later stage.

[0004] Therefore, it is necessary to provide a new buffer structure for CNC bending machines to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a buffer structure for a CNC bending machine.

[0006] The buffer structure of the CNC bending machine provided by this utility model includes: a frame, on which a bending knife is mounted, and buffer components are provided on both sides of the top of the frame;

[0007] The buffer assembly includes a mounting frame, which is mounted on the frame. The mounting frame has several evenly distributed slots inside, and a slidingly connected support plate is inserted into the slot. The support plate has several evenly distributed buffer springs, and the specifications of the buffer springs on each layer of the support plate are different.

[0008] Preferably, a fixedly connected support frame is mounted on the frame, and positioning rods are provided at the four corners of the top of the support frame, and the same slidingly connected placement plate is sleeved on the outer wall of several of the positioning rods.

[0009] Preferably, the top center of the placement plate has symmetrically distributed mounting grooves, and a rotatably connected guide roller is mounted inside the mounting groove, with the outer wall of the guide roller being at the same level as the top of the placement plate.

[0010] Preferably, a support frame is mounted at the center of the top of the frame, and a cylinder is mounted inside the support frame, with the bottom end of the cylinder fixedly connected to the top of the bending knife.

[0011] Preferably, the support frame has several evenly distributed through slots on both sides, and a support rod is inserted into the through slot.

[0012] Preferably, the mounting frame has a plurality of evenly distributed fixing magnetic sheets on one side wall away from the center of the frame, the fixing magnetic sheets being positioned opposite the slots, and the support plate has a mating magnetic sheet on one side wall near the fixing magnetic sheets, the mating magnetic sheet and the fixing magnetic sheet being attracted to each other.

[0013] Preferably, a support cylinder is provided on the side of the outer wall of the support plate near the support frame, and the inner wall specifications of the support cylinder are the same as the outer wall specifications of the support rod.

[0014] Compared with related technologies, the buffer structure of the CNC bending machine provided by this utility model has the following beneficial effects:

[0015] 1. By incorporating a buffer component, this utility model allows the spring to be adjusted to a model compatible with the bent metal plate during use, thus enabling the device to smoothly buffer bent metal plates of different specifications and thereby improving its applicability.

[0016] 2. This utility model installs a rotating guide roller at the bend of the plate. During the bending process of the metal plate, the metal plate, which is subjected to extrusion force and moves downward, will drive the guide roller to rotate by resisting it. This can transform the sliding friction force of the metal plate during movement into rolling friction, reduce the friction force of the metal plate during movement, make the bending of the metal plate smoother, and reduce the probability of the metal plate being scratched or damaged due to sliding friction.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 6 The present invention provides a buffer structure for a CNC bending machine, the buffer structure of which includes: a frame 1.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 6 The frame 1 is equipped with a bending blade 2, and buffer components 4 are provided on both sides of the top of the frame 1. The buffer components 4 include a mounting frame 41, which is set on the frame 1. The mounting frame 41 has several evenly distributed slots 411 inside, and a sliding support plate 42 is inserted into the slot 411. The support plate 42 is equipped with several evenly distributed buffer springs 43, and the specifications of the buffer springs 43 on each layer of support plate 42 are different. Several evenly distributed fixed magnetic pieces 412 are provided on the side wall of the mounting frame 41 away from the center of the frame 1. The position of the fixed magnetic pieces 412 is opposite to the position of the slots 411. The side wall of the support plate 42 near the fixed magnetic pieces 412 is equipped with a mating magnetic piece 422. The mating magnetic piece 422 and the fixed magnetic piece 412 attract each other. The outer wall of the support plate 42 is equipped with a support cylinder 421 near the support frame 11, and the inner wall specification of the support cylinder 421 is the same as the outer wall specification of the support rod 5.

[0028] It should be noted that by setting buffer springs 43 of different specifications on each support plate 42, the springs can be adjusted to match the model of the bent metal plate as needed during use, so that the device can smoothly buffer bent metal plates of different specifications, thus improving the applicability of the device.

[0029] By attracting each other between the fixed magnetic plate and the mating magnetic plate, the unused support plate 42 can be fixed in place during use, so that it can be stably stored in the mounting frame 41, thereby preventing the remaining support plate 42 from sliding randomly during operation.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 6 A fixed support frame 12 is mounted on the frame 1. The four corners of the top of the support frame 12 are provided with positioning rods 121. The outer walls of several positioning rods 121 are fitted with the same slidingly connected placement plate 3. The center of the top of the placement plate 3 is provided with symmetrically distributed mounting grooves 31. The inside of the mounting grooves 31 is provided with rotatably connected guide rollers 32, and the outer wall of the guide rollers 32 is at the same level as the top of the placement plate 3.

[0031] It should be noted that by setting up a rotating guide roller 32 at the bend of the placement plate 3, during the bending process of the metal plate, the metal plate, which is subjected to extrusion force and moves downward, will drive the guide roller 32 to rotate by resisting it. This can convert the sliding friction force when the metal plate moves into rolling friction, reduce the friction force when the metal plate moves, and make the bending of the metal plate smoother, and reduce the probability of the metal plate being scratched or damaged due to sliding friction.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 6 A support frame 11 is mounted at the center of the top of the frame 1. A cylinder 112 is mounted inside the support frame 11, and the bottom end of the cylinder 112 is fixedly connected to the top of the bending knife 2.

[0033] It should be noted that by connecting the cylinder 112 to the bending knife 2, the working cylinder 112 can drive the bending knife 2 to move and bend the sheet metal.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 6 Several evenly distributed through slots 111 are provided on both sides of the support frame 11, and support rods 5 are inserted inside the through slots 111.

[0035] It should be noted that, by setting the through groove 111 and the support rod 5, when the support plate 42 is pulled outward, when the support cylinder 421 moves to the position opposite to the through groove 111, the end of the removed support plate 42 can be supported by inserting the support rod 5 into the through groove 111 and the support cylinder 421, thereby making the support plate 42 unfold more stably.

[0036] The working principle of the buffer structure of the CNC bending machine provided by this utility model is as follows;

[0037] During use, the buffer spring 43, which is adapted to the required bending plate, can be pulled out from the inside of the mounting frame 41 as needed. When the support cylinder 421 at the end of the support plate 42 is in a relative position with the through groove 111 in the support frame 11, the support rod 5 can be taken out and inserted into the through groove 111 and the support cylinder 421 for fixation, thereby fixing the inserted support plate 42.

[0038] After adjusting the required buffer spring 43, the worker can place the sheet material to be bent on the placement plate 3, and then control the cylinder 112 to work. The working cylinder 112 can drive the bending knife 2 to move downward to bend the sheet material.

[0039] During this process, when the compressed sheet moves downward and comes into contact with the guide roller 32 on the placement plate 3, it can drive the guide roller 32 to rotate, thereby changing the sliding friction of the sheet moving during bending into rolling friction, which can reduce the friction of the sheet bending and make the bending movement of the sheet smoother.

[0040] When the plate is subjected to the pressure of bending, causing the placement plate 3 to move downward, the buffer spring 43 that unfolds on the support plate 42 can absorb and buffer the downward pressure, thus completing the use of this device.

[0041] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
